Busymail is a Model Context Protocol (MCP) server: Read, organise and send from your existing email accounts. Nothing sends without your approval. In practice that means any MCP-compatible AI assistant can call Busymail's tools directly — the model decides when to use them in a conversation or agent run.
It's a hosted (remote) server — point your client at https://busymail.app/mcp and you're connected, with nothing to install locally. The current release is v1.0.0.
Busymail is listed under Communication on mcp.site and works with any MCP client — Claude Desktop, Claude Code, Cursor, VS Code, Windsurf, Zed and the rest of the ecosystem — using the install snippets below.
